Hear Siren

All demos are raw Siren outputs - no effects.

Nuanced Timbres

Siren responds to the fine-grained details in your prompt. So when you want a piano, you can choose whether it belongs in a meditation chamber, a 70s power ballad, or something in between.

Made for Layering

Layer Siren tracks to paint rich, wide soundscapes with ease. This orchestra was made with three simple prompts all playing the same notes. Play around with the controls to reveal diverse possibilities.

Past, Present, and Future

Following the vocabulary in your prompt, Siren can shift from synthesizing warm recreations of nostalgic instruments to pioneering futuristic instruments with unprecedented textures.
